Place it as the bed under the full scene, from the opening shot through the build, then end the sequence with an evil laugh right on the reveal, before cutting to the reaction shot that pays off the moment.
关于此声音
This is a horror music clip that runs for about 77 seconds, built as a sustained background track rather than a short sting. It gives a listener a tense, unsettling feeling of dread, as if something bad is about to happen off screen, and it holds that pressure instead of resolving into a jump scare or a punchline.
